the giving rats

I tracked by train to see my rat people in upstate New York, I was surprised to see how big they had become. They grow so fast!. They have nice glossy coats and are keeping themselves clean so they don't smell. Their tails are a bit dirty but that is not unusual because for some reason rats don't really clean there tails. I heard that one of my rats was nipping people that change their cages but I never got bitten only happy chatter and received lots of scratches from their long nails
